CarbonFin Outliner isn’t the most frequently updated app on the App Store, but I still think it offers a superior outlining experience than any other outliner for the iPhone. On the iPad, I’m torn between Outliner and The Omni Group’s update to OmniOutliner (custom keyboard shortcuts? That’s business), but Outliner is capable of syncing with Dropbox and directly to an iPhone version, which makes it preferable to OmniOutliner and OmniPresence in some aspects.

Outliner was recently updated with iOS 7 support, which means interface changes that make the app’s chrome more subdued in favor of content. This is an overly used expression these days (by me as well), but it’s true, and, in Outliner’s case, I think it benefits the app. Outlines stand out and buttons are easily recognizable; the app retains the menus it always had to allow you to indent or outdent lines with ease.

The app didn’t get iOS 7 features, but, according to the developer, background sync is on the roadmap. Outliner is a good outlining tool, albeit rarely updated with major additions. On the iPhone, I don’t think other similar apps come close to Outliner’s simplicity and elegance yet. I’d recommend getting the Universal version for $4.99 while hoping for updates in the near future.
